2. SYN/ASYN Serial Port - Provides an X.21/RS422/RS232 synchronous / asynchronous serial port using a
DB25 connector.
3. GPS - Provides GPS capabilities using an SMA male connector.
4. ISDN - Provides an ISDN Basic Rate Interface (BRI) via an RJ45 port. This can be configured either
as a TE (terminal endpoint) or as NT-1 (network termination). The option also includes an additional
asynchronous serial port via a second RJ45 port.
5. Telemetry 1 I/O Interface - Provides 4 opto-isolated digital input ports and 1 opto-isolated digital output
port. It also provides a relay I/O port, a voltage monitoring port, and internal temperature monitoring.
6. Telemetry 2 I/O Interface - Provides 4 isolated analog I/O ports and 4 non-isolated digital I/O ports.
7. Fleet I/O Interface - Provides CAN and J1708 interface, GPS, 4 non-isolated digital I/O ports, ignition
sense port, and a 3 axis accelerometer.
8. PSTN - Provides a PSTN interface via an RJ45 connector that can be used to dial out and receive calls.
9. ISDN-U/PSTN - Provides an ISDN-U interface suitable for the USA plus PSTN interface. It can be
configured for Bell-103 modulation in leased line mode as well as a normal PSTN interface.
10. DialServ - This RJ11/FXS connection converts a PSTN analog modem to a RS-232 serial signal.
